Abstract

PURPOSE:To insert a picture to a desired position accurately at all times by inserting and recording a new picture signal while leaving horizontal and vertical synchronizing signals recorded in advance on a tape recorded already as they are. CONSTITUTION:When the tape 1 after recording is reproduced and the tape comes to a desired position of insertion while monitoring the tape by a monitor 11, an inserting command is given to a recording/reproducing changeover timing circuit 8 and then recording/reproducing changeover switches 3a, 3b, 4a, 4b are switched to the recording terminal P. A timing signal generated from the changeover timing circuit 8 is generated only at the video signal period of a reproduced video signal (Fig. a) as shown in Fig. (b) and does not appear at the synchronizing signal period. Thus, when the insertion command is given to a device in the normal reproducing mode, the changeover timing signal is transmitted from the timing circuit 8 only during the period given by the command afterward and the recording mode is obtained.

<Prior art> In a conventional VTR having an electronic editing function, when inserting and recording a title picture or the like at a desired part of a recorded tape, a signal previously recorded on multiple video tracks at the desired part is used. This is done by erasing the data from all tracks and then newly recording separate video signals for multiple fields on those tracks, thereby performing so-called insert editing.
□Problems> Therefore, when performing insert editing on a VTR as described above, since the reproduced image cannot be monitored, there is a risk that a new image may be inserted into an undesired location on the tape.

The operation of inserting and editing a desired title into a portion of the recorded tape I in the electronic editing apparatus configured as described above will be described below. First, a desired title is written on the subject 13 in advance, and the subject 13 with the title written thereon is imaged by the television camera 12. On the other hand, the recording/reproduction changeover switches 3a, 8b, 4a, and 4b are normally switched preferentially to the reproduction side terminal [F] and are in the reproduction mode, as shown in the figure. Therefore, at this time, the video signal reproduced from the recorded tape by the video head 2 is inputted to the reproduction system signal processing circuit 5 via the changeover switches 3a and 3b, where it is subjected to appropriate signal processing, and then transferred to the changeover switch 4a. , i4b to the monitor receiver 11
At this time, the reproduced image of the tape is displayed on the monitor receiver 11. In addition, during such reproduction, the reproduced video signal obtained from the reproduction system signal processing circuit 5 is supplied to the synchronization separation circuit 7, where the horizontal and vertical synchronization signals included in the video signal are separated, and this synchronization signal is supplied to the recording/reproduction switching timing circuit 8 and the television camera 12, thereby synchronizing each circuit.

In this way, the recorded tape l is played back, and while the played image is monitored on the monitor receiver 11, when the played image reaches the position where the title is desired to be inserted, an insert command is given to the recording/playback switching timing circuit 8. At this time, a switching timing signal is generated from the switching timing circuit 8, and this causes the recording/reproduction changeover switch 3 to be activated.
All terminals a, 3b, 4a, and 4b are switched to the recording side terminal [F].

Note that the timing signal generated by the switching timing circuit 8 is generated only during the video signal period of the reproduced video signal (shown in FIG. 2(a)) as shown in FIG. 2(b), and is not generated during the synchronizing signal period. It is assumed that the pulse width does not appear and that the pulse width can be arbitrarily set by the switching timing circuit 8.

As a result of the above, when the insert command is not given in the device in the normal playback mode, the switching timing signal is derived from the recording/playback switching timing circuit 8 only while this command is not being given. During this time, the video signal representing the title captured by the television camera 12 is appropriately processed by the recording system signal processing circuit 6, and then supplied to the monitor receiver via the changeover switches 4a and 4b. At the same time, the selector switch 8a is turned on again.
The signal is supplied to the video head 2 via 8b.

Therefore, at this time, recording and playback are repeated alternately in the video head 2, and as shown by diagonal lines in FIG.
In particular, during the video signal period, a new video signal from the external television camera 12 is recorded superimposed or in place of the original video signal, thus performing insert editing. Meanwhile, on the monitor receiver 11, a part (or all if necessary) of the reproduced image is replaced with the title captured by the television camera +2 and displayed.

Note that during the insert editing operation described in (h), the control head 9 controls the recorded tape 1 in the same way as the operation of a normal VTR.

Effects> According to the electronic editing device of the present invention, recording is performed only during the video signal period in synchronization with the synchronization signal in the reproduced video signal reproduced from the tape when a recorded tape is reproduced, as shown in item L. / A playback switching timing signal is derived, and based on this signal, the mode is temporarily switched to recording mode, so that external video signals from a television camera, etc. are recorded only in a part of the recorded tape, especially during the video signal period. Therefore, it is possible to perform insert editing while playing back a recorded tape and monitoring the played image on a monitor receiver.
